I am running kernel 2.6.31-17-generic and discovered 'ifconfig wlan0 up' does not work,
ifconfig wlan0 netmask up
works fine!!!

'ifconfig wlan0 down' when the device is already down won't let it come back up without a system reboot.

Basically, it seems any configuration error, no matter how slight, will hose 'ifconfig' until a system restart.
